Around 300,000 spectators are expected to attend the Paris Olympics opening ceremony this summer. The ceremony will break from tradition by taking place along the Seine River, not in a stadium. The July 26 ceremony will traverse a 3.5-mile stretch through central Paris with 160 boats carrying athletes on the water as crowds line the riverbanks.

However, such plans come with security risks, particularly with ongoing conflicts in Ukraine and the Middle East.

Earlier in April, French President Emmanuel Macron expressed concerns about potential security threats to the Games, including from Russia.

“I have no doubt that the Games will be a target for Russia, including in the field of information,” Macron said during the inauguration of the Olympic Aquatics Centre in Saint-Denis, north of Paris.
